You’ve probably heard about editing product images to drive sales and conversion. However, optimizing eCommerce images is a slightly different thing. Unlike traditional image post-processing, this approach doesn’t focus on improving visual aesthetics.

Instead, the main goal is to improve the images in a way that ensures they load quickly, consume less bandwidth, offer a seamless user experience, and ultimately improve SEO performance. It’s all about making your eCommerce website more efficient and effective.

Why is image optimization important for eCommerce?

Regarding eCommerce, image optimization is a crucial aspect of maximizing your online success.

Let’s explore the importance of eCommerce image optimization and how it can benefit your online business.

Enhanced user experience

When customers visit your website, they expect a smooth and visually pleasing experience. Optimizing your eCommerce product images ensures that they load quickly and appear sharp and vibrant.

This creates a positive first impression and encourages users to explore your products and engage with your content.

Improved website speed

Nowadays, nobody likes to wait for a website to load. If your eCommerce site is sluggish, potential customers will quickly lose interest and move on to your competitors. eCommerce Image optimization plays a vital role in reducing file sizes and optimizing loading times.

In this way, you can ensure your images are lean and mean. As a result, you can significantly improve website speed, keeping users engaged and increasing the likelihood of conversions.

Boosted search engine rankings

Search engines like Google consider various factors when determining the ranking of a website. One important aspect is the speed at which a page loads.

Optimizing your eCommerce images will improve your website’s loading speed, which search engines love.

As a result, your site has a higher chance of ranking higher in search engine results, driving more organic traffic to your online store.

Increased visibility and CTR

Eye-catching product images are essential for attracting potential customers. When you optimize your eCommerce images, you make them more visually appealing, increasing their impact and capturing the attention of your target audience.

Higher-quality images can lead to higher click-through rates, as users are more likely to click on attractive thumbnails in search results or eCommerce marketplaces.

Mobile-friendly optimization

With the increasing use of mobile devices for online shopping, it’s essential to make sure your eCommerce images are optimized for mobile viewing.

Mobile-friendly optimization includes considerations such as responsive design and compressed image sizes, which enables faster loading and a seamless user experience across different devices.

Simply uploading product images is not enough anymore. Search engines analyze both text and images on your website. So to boost your site’s visibility and improve image SEO, you need to optimize your images properly.

Whether you’re looking for Shopify image optimization tips or best practices for big commerce image optimization the following tips will help you out.

Choose the right image file format

There are several options for image file format including JPEG, PNG, GIF, and WebP. Each format has its own strengths and weaknesses.

Here is a list of image formats and their strength and weaknesses:

JPEG (Joint Photographic Experts Group)


  • Compression with minimal loss in quality.
  • Offers a good balance between image quality and file size.
  • Compatible with most web browsers and devices.


  • Not ideal for images with sharp edges or solid colors.
  • Lossy compression can degrade image quality over multiple saves.

PNG (Portable Network Graphics):


  • Lossless compression maintains image quality.
  • Support for transparency.
  • Good for images with sharp edges or solid colors.
  • Suited for images that require a high level of detail.


  • Larger file sizes compared to JPEG and WebP.
  • Not as widely supported by older browsers.

GIF (Graphics Interchange Format)


  • Support for animation.
  • Large file sizes.


  • Limited to 256 colors.
  • Not suitable for images with a wide range of colors.

WebP (Web Picture)


  • Smaller, richer images compared to other formats.
  • Supports transparency and animation.
  • Superior lossless and lossy compression.


  • Not as widely supported by older browsers.
  • Limited support for advanced editing features.

Our Recommendation: While JPEG, PNG, and GIF are widely used and gained a lot of popularity in the past, WebP is the future of web images that can not only make your website faster but also save a lot of disk space.

According to Google “WebP lossless images are 26% smaller in size compared to PNGs. WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller than comparable JPEG images at equivalent SSIM quality index.”

WebP images strike a perfect balance between quality and file size. So if you have an eCommerce store that contains a lot of product images go for WebP instead of JPEG. As it can speed up your website loading and takes a lot less space.

Compressing images for faster loading times

One of the most critical aspects of eCommerce image optimization is file compression. There are two types of compression: lossy and lossless. Lossy compression reduces the file size by permanently removing some of the image data.

While this can result in a smaller file size, it may also lead to a slight loss in image quality. Lossless compression, on the other hand, reduces the file size without sacrificing any image quality.

Because online sales can significantly rely on high-quality product photographs that are used to drive sales on Amazon and other eCommerce websites, using lossy compression might not be the best idea.

To compress your images, you can use various online tools or plugins specifically designed for image optimization. These tools will enable you to compress images without compromising their visual quality.

Additionally, some Image Content Delivery Networks (CDNs) like Sirv and Bytescale offer automatic image optimization, which can further improve your website’s performance.

Naming and Alt text optimization

When it comes to eCommerce image optimization, the file name and alt text play a crucial role. Search engines rely on this information to understand the context and relevance of your images.

When naming your image files, it’s essential to use descriptive, keyword-rich names that accurately represent the content of the image. Avoid generic names like “img001.jpg” and instead opt for descriptive names like “blue-velvet-sofa.jpg.”

This not only helps search engines understand the content but also improves the accessibility of your website for visually impaired users who rely on screen readers.

Alt text, or alternative text, is a brief description that provides context to search engines and visually impaired users when the image cannot be displayed. It is crucial to include relevant keywords in your alt text while ensuring it accurately describes the image.

However, avoid keyword stuffing and keep the alt text concise and meaningful.

Optimizing image size and dimensions

One of the most common mistakes eCommerce store owners make is uploading images that are larger than necessary. Large image files can significantly slow down your website, leading to a poor user experience and lower search engine rankings.

To optimize your image size and dimensions, consider the following steps:

One of the most common mistakes eCommerce store owners make is uploading images that are larger than necessary. Large image files can significantly slow down your website, leading to a poor user experience and lower search engine rankings.

To optimize your image size and dimensions, consider the following steps:

Use the appropriate image dimensions

Before uploading an image, make sure its dimensions match the space where it will be displayed on your website. This helps avoid the need for resizing, which can result in pixelation or distortion.

Resize and crop images

If you have high-resolution product photos, consider resizing them to a more appropriate size for web display. You can use image editing software or online tools to resize and crop your images without losing quality.

Using responsive images for mobile optimization

With the increasing use of mobile devices for online shopping, it’s crucial to ensure your eCommerce website is optimized for mobile users.

Responsive images adapt to different screen sizes and resolutions, providing an optimal viewing experience across devices.

To implement responsive images, try out the following techniques:

Use CSS media queries

CSS media queries allow you to specify different image sizes for different screen sizes. By using this technique, you can serve appropriately sized images to mobile users, reducing the amount of data they need to download.

Implement the srcset attribute

<img srcset="" src="" alt="">

The srcset attribute allows you to provide multiple versions of an image and let the browser choose the most suitable one based on the user’s device capabilities.

This ensures that users receive the best possible image quality without unnecessary data usage.

Implement lazy loading

Lazy loading is an eCommerce image optimization technique that delays the loading of images until they are visible on the user’s screen. This helps reduce the initial page load time and improves the overall performance of your eCommerce website on mobile devices.

Implementing image sitemaps for better indexing

An image sitemap is a specialized sitemap that provides search engines with information about the images on your website. Creating and submitting an image sitemap can ensure that search engines crawl and index your images effectively.

To create an image sitemap, follow these steps:

Generate an XML sitemap

There are several online tools and plugins available that can help you generate an XML sitemap specifically for images.

Include image-specific tags

Within the XML sitemap, include additional image-specific tags such as image captions, titles, and license information. These tags provide search engines with more context about your images and improve their understanding.

Submit the sitemap to search engines

Once you have generated the image sitemap, submit it to search engines like Google and Bing through their respective webmaster tools. This ensures that search engines are aware of all the images on your website and can index them accordingly.

Monitor the performance

After implementing eCommerce image optimization techniques, it’s essential to monitor the performance of your images and make any necessary improvements.

This can be done using website analytics tools that provide insights into your website’s performance, including image loading times and user engagement.

By regularly analyzing your image performance data, you can identify any potential issues, such as slow-loading images or high bounce rates, and take appropriate action.

This may involve further optimizing your eCommerce images, reviewing your image SEO strategies, or making changes to your website’s design or layout.

Woocommerce image optimization tips for SEO

WooCommerce is an excellent platform for creating and managing SEO-friendly eCommerce stores. If you have a WooCommerce online store, here are a few eCommerce image optimization tips to consider:

Consider optimizing your thumbnails

WooCommerce automatically resizes your images into different dimensions. However, for the best results in terms of file size, it is better to optimize them manually. You’ll want to strike a balance between usability and keeping the size as small as possible.

Here are the steps to follow:

◾ Access your WooCommerce settings

Log in to your WordPress dashboard and navigate to WooCommerce > Settings

◾ Go to the Product tab

Once you’re in the WooCommerce settings, click on the “Product” tab.

◾ Choose the “Display” option

In the Product tab, you’ll find a sub-menu. Click on the “Display” option.

◾ Adjust thumbnail dimensions

Look for the “Product Images” section. Here, you can set the dimensions for your product thumbnails.

◾ Consider usability

While you want to keep the size small, Ensure that the reduced thumbnail size still allows customers to see and identify the product details easily.

◾ Save changes

Once you have adjusted the thumbnail dimensions according to your preferences, don’t forget to save the changes.

Note: If you have already uploaded product images before changing the thumbnail dimensions, you may need to regenerate the thumbnails to ensure they reflect the new size. You can use plugins like “Regenerate Thumbnails” to automate this process.

Optimize your image URLs

When it comes to SEO for Woocommerce sites, it’s essential to understand that not only do your webpage contents matter, but the structure of your image URLs also holds significant importance.

Below are some tips to ensure your WooCommerce image URLs are SEO-optimized:

  • Enable Permalinks

It’s important to make sure that permalinks are enabled in your WooCommerce store. By doing so, you’ll have the ability to craft personalized URL structures for your product and category pages, as well as for your image URLs.

  • Use Descriptive File Names

When uploading images to your WooCommerce store, give them descriptive file names that accurately represent the content of the image.

  • Include Relevant Keywords

Incorporate relevant keywords into the image’s URL structure to improve its search engine visibility. For example, if you’re selling red shoes, a URL like is more descriptive and SEO-friendly than “”.

  • Separate Words with Hyphens

Use hyphens (-) to separate words in your image URLs. This improves readability for both search engines and users.

  • Short and Meaningful URLs

Keep your image URLs concise and meaningful. Avoid using long strings of random characters or numbers.
